STARTING .AND IGNITION APPARATS AND SYSTEM.

Specification of Letters Patent.

Patenten oet. 24, 191e.

Application filed March 11, 1914. lSerial No8/23,871.

To all whom t may concern Be it known that I, RICHARD VARLEY, a citizen of the United States of America, residingv at Englewood, in the county hf Bergen and State of New Jersey, have invented new and useful Improvements in Starting and Ignition Apparatus and Systems, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, which form part of this specification.

This invention aims to provide a new and improved form of starting apparatus whereby the torque of a moving element, such as an electric motor, may be multiplied sufficiently to e'ect turning over or driving of the engine crank shaft for starting of the engine.

As such a device, some of the objects sought are the provision of mechanism which is simple, compact and self-contained in construction and whereby the driving element can not be connected to the engine during normal running of the latter, in a manner or under conditions that. might prove injurious to the starting apparatus, and means for preventing transmission of strains to the starting apparatus upon a reverse drive of the engine, as by back firing.

I also aim to provide othernew and improved features of construction which, together. with the above indicated features, will be hereinafter more fully described and claimed.

. will now describe my invention so that others skilled in the art towhich it appertains may understand and constructthev same, it being premised however, that while reference is made to the accompanying' drawings, I do not desire to limit myself thereto as the invention is capable of being embodied in other apparatus.'

FigureV 1 is a vertical sectional View through engine starting apparatus, showing'the same in association with an electric motor which is illustrated as being in elevatiomand partly broken away; Fig. 2 is an elevational view showing centrifugal lock mechanism for preventing establishment of connection between the engine and starterlsubsequenily to starting and during normal self-propulsion of the engine, in the construction set forth in Fig. l.

A suitable starting motor 2 which may be of the usual type of motor employed in the starting equipment of autovehicle construction, is provided with an extension 6a which forms a support for a head member llu of .a one direction or irreversible clutch of the usual construction having one of its parts in the form of a ring gear l0. The clutch member 'lla is tixedly keyed to a shaft 3 so that the shaft at one end is supportedby the motor shaft, a bushing or bearing 78 preferably being interposed between the clutch member and the motor shaft. The opposite end of the shaft is mounted in ball bearings 79 carried by a frame 8O which may form the usual gear casing at the forward end of the engine. Journaled in ball bearings 8l is another shaft 82 which may constitute the shaft for a gear 83 which may comprise, in function, one of the usual timing gears within the gear casing at the front of the engine, for synchronous driving of a generator or magneto electric machine e2". Loosely carried by-theshaft 82 is a gear 84E meshing with which is a pinion 85 fixed tothe shaft 3. The gear 84 is shiftable along the shaft by means of a suitable yoke mechanism 86 and lever 87 which may connect with the running board of the vehicle. The gear 84: is provided with pockets or recesses 88 for 'reception of clutch'dogs or fingers 89 carried by the face of the gear 83. The gear 83 is recessed to receive a plurality of radially eXtensible weight members 90 that are held normally iny a retracted position by means of springs 91 which connect with pins 92 of the weights. The inner ends of the weights lie in recesses 93 formed in the shaft 82 and have forwardly extending finger portions 94 the peripheral edges of which lie substantially iiuslL with the surface of the shaft when the weights are in retracted position. After the engine becomes self-propulsive and the speed of the gear 83 is such as to'set up centrifugal expansion of the weights counteractively to the tension of the springs 91, the fingers 94 va second member driven by the engine,-

move outwardly from the shaft recesses 93 to the position shown in dotted lines in Fig. 1. Therefore, should the gear 84 be shifted toward the gear 83 during self-propulsion of the engine at such speed as to effect eX- pansion of the weights, the shifted gear will on the journal 8 of the gear 7, transmit power to the rin gear 1001 the irreversible clutch, for startmg of the engine through the gears 85, 84 and 83. Should the gears 83 and 84 remain in clutch engagement during self-propulsion of the engine, the one direction clutch construction shown and described would permit of driving of the shaft 3 without spinning the motor at high speed. Immediately upon de-clutching of the gears, the fingers 94 of the Weights Would assume a position prohibitive to clutch engagement.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. In starting apparatus for combustion engines, a rotatable member for transmitting power to the engine, a second member driven, by the engine, means for connecting the members together, comprising a plurality of clutch elements one of which is adapted to be driven by the first named member, and a centrifugally actuable device for rendering said clutch element ineffective.

2. In starti apparatus for combustion engines, a m or, a rotatable member for transmitting power therefrom to the engine, gearing connecting the motor and member,

means for connecting the members together, comprising a plurality of clutch elements one of which is adapted to be driven by the first named rotatable member, and a centrifugally responsive device for rendering said connecting means ineffective.

3. In starting apparatus for combustion engines, a motor, a gear, an 'irreversible clutch connecting the gear and motor, a second gear driven by the engine, means for connecting one gear with the other for starting of the engine, and centrifugally responsive means for preventing said connection of the gears.

4. In starting apparatus for combustion engines, a rotatable member for transmit- Leonesa and member, a second member driven by the engine, means for connecting the members together, comprising a second clutch, and a centrifugally responsive device for rendering the second clutch ineiective.

6. In starting apparatus for combustion i engines, a motor, a rotatable member for transmitting power therefrom to the engine, means connecting the motor and member, comprising gearing and an irreversible clutch,'a second member driven by the engine, meansl for connecting the members together for starting of the engine, and means associated with the connecting means, for rendering said latter means ineffective.

7. In starting apparatus for combustion engines, a clutch memberdriven by the engine, a rotatable member for transmitting power to the engine and shiftable into cooperative engagement with the clutch memn ber,l and' a centrifuga-ily responsive device associated with the clutch and adapted to lock the rotatable member against shifting to clutch engaging position.

8. In starting apparatus for combustion engines, a member drivenby the-engine, a rotatable clutch member fixed thereto, a second rotatable member shiftable into clutch. engagement with and adapted to transmit power to the first member, and a centrifugally responsive device carried by the first member and adapted to prevent clutch engagement of the members.

9. In starting apparatus for combustion engines, a rotatable clutch member driven by the engine, a rotatable member slidable into and out of engagement with and for transmitting power to the clutch member, and a locking finger carried by the clutch member and movable to a position to'prevent clutch engagement by the second member. A

10. In starting apparatus for combustion engines, a rotatable clutch member driven by the engine, a rotatable member slidable Vinto and out of engagement with and for transmitting power to the clutch member, and a centrifugally responsive lockng member carried by the clutch member and movable to a position whereby the second rotatable member may be locked against clutch engagement.
